FFIQEQ UNTTED STATES PATENT CORNELIUS COLLINS, OF ALI-BIA, IOIVA, ASSIGNOR OF ONE-HALF TO GEORGE W. MOBURNEY, OF SAME PLACE GARDEN PLOW, CULTIVATOR, 86C.

SPECIFICATION forming part of Letters Patent No. 412,840, dated October 15, 1889.

Application filed March 8, 1889. Serial No. 302,448.- (N model.)

To all whom it may concern.- I the standard is secured a plowshare d, of the Be it known that I, CORNELIUS COLLINS, a usual or any suitable form, and bolted to the citizen of the United States, residing at Albia, lower end of said standard and projecting in the county of Monroe and State of Iowa, upward therefrom is a single plow-handle e,

have invented a new and useful Improve the upper end of which is adapted to extend ment in Garden Plows, Cultivators, Harrows, between the rear portions of the bars A and &c., of which the following is a specification. to be grasped by one hand of the operator,

My invention relates to an improvement in whereby he is enabled to direct the plow at garden plows, cult-ivators, harrows, &c.; and any desired depth and to swing the same IO it consists in the peculiar construction and laterally to avoid obstructions or plants. combination of parts hereinafter more fully I will now describe myimproved cultivator described, and particularly pointed out in attachment.

50 nected to the casting F. To the lower end of I will now describe my improved harrow I00 attachment, which comprises a V-shaped harrow-frame a having the barrow-teeth b and provided with the handle 0 and the braces d. The handle has its front end secured to the front of the barrow-frame, and the braces have their upper ends bolted to the handle and their lower ends bolted to the cross-beam at the rear of the barrow-frame. A draftiron 6 is bolted on the front side of the handle, near the lower end thereof, and has an eye formed in its upper end, to which is linked a hook f, the latter being adapted to engage the eye of the swiveled bolt, and thereby connect the harrow attachment to the main frame. The operator manipulates the harrow attachment by grasping the handle 0, as is obvious.

Having thus described my invention, I claim 1. The frame A, having the swiveled bolt f, in combination with the rod 9, passed through an eye at the lower end of the bolt and having the hook or stop at its frontend, the beam carrying the implement to act on the soil and having its rear end loosely connected to the rear end of said rod, and the linkarm having its upper end loosely connected to and adapted to slide longitudinally on the rod and its lower end pivotally connected to the lower end of the frame, substantially as described.

2. The frame comprising the parallel compound curved bars A, the yoke B, connecting the rear ends of the said bars, the shaft connecting the front ends of the bars, and the driving and supporting Wheel mounted on said shaft, substantially as described.

3. The frame having the swiveled bolt f, the rod 9, connected at its front end to said bolt and arranged at right angles thereto, and the beam carrying the implement to act on the soil, said beam being pivotally and loosely connected to the rod g, so as to slide thereon, as set forth.

4:. The frame having the wheel D and bars A, combined with the beam carrying the implement to act on the soil, the swiveled bolt f on the frame-bars A, the beam of the implement being connected to the bolt f, as set forth. I

5. The frame comprising the parallel bars A, shaped and curved substantially as shown, and having the curved yoke B connecting their rear ends, the wheel D, journaled between their front ends, and the casting F, connecting the bars A in rear of the wheel and providing a bearing for a pivot-bolt, to which the implements are connected, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in presence of two witnesses.

CORNELIUS COLLINS.
